Abstract

To examine the stability in the bag in foldable silicone IOL implantation and determine its effect on visual acuity. This study comprised 66 eyes that had phacoemulsification with three-piece foldable silicone intraocular lens(IOL) implantation that were prospectively evaluated about 2 months after surgery. The examination included the status of the haptic and optic placement, extent of posterior capsular capsular opacification(PCO), and the best corrected visual acuity. Sixty-five eyes had an in-in haptic placement, one eye had in-out placement, and there was no eye in out-out placement. Capsular capture occurred in 13 eyes(19.70%). The extent of POC in eyes with capsular capture was greater than in those withot capture. But the best corrected visual acuity in eyes with capsular capture made no difference to those without capture. In addition, eyes with in-out and out-out haptic placement had worse PCO than the eyes with in-in placement. There was a high incidence of capsular capture after silicone IOL implantation. This complication, along with the undesirable placement of the haptics, led tod PCO and was anticipated visual inpairment in long term follow-up. Therefore proper amount of continuous curvilinear capsulorhesix opening and complete placement of lens in the bag ahould be necessary.
